On February 16, the Supreme Court had given the Centre six weeks to form the board, which was to take control of the dams across river Cauvery and distribute the waters to Karnataka, Tamil Nadu, Kerala and Puducherry according to the formula of the Cauvery tribunal. The deadline ends today.
The Centre's decision to get back to the court came after a disagreement between Tamil Nadu and Karnataka over the structure of the body to be formed - a confusion that rose out of the phrasing of the Supreme Court order.
The court did not use the words Cauvery Management Board, it said a scheme'. In its 2007 order, the Cauvery water tribunal recommended setting up a board with a chairman, who would be an officer of the chief engineer's rank. The board, it said, would have two members and a secretary.
The Supreme Court order of February 16 had shrunk Tamil Nadu's share. The court had increased the 270 thousand million cubic feet (tmcft) share of Cauvery water for Karnataka by 14.75 tmcft and reduced Tamil Nadu's share, while compensating the latter by allowing extraction of 10 tmcft groundwater from the river basin. The issue of drinking water had to be placed on a "higher pedestal", the court had said.
